Hydroxypropyl starch ether
Hydroxypropyl starch ether is a kind of natural plant-based raw material that has been modified and highly The white powder obtained by etherification reaction and then spray drying does not contain plasticizer. Its powder has good fluidity and good water solubility, and its aqueous solution is transparent and colorless with good stability. It is stable to acid and alkali, its melting temperature is lower than that of original starch, and its cold and hot viscosity changes are more stable than that of original starch. The ice melt stability and transparency after etherification are improved.
